What makes the metric units precise and accurate?

Answer 1

Metric units have many advantages over Imperial units but precision and accuracy are not amongst them. Precision and accuracy depends on the individual units in use.

For example,

A kilometre is more accurate than a mile,

A furlong is more accurate than a kilometre,

A metre is more accurate than a kilometre,

A yard is more accurate than a metre,

A foot is more accurate than a metre,

An inch is more accurate than a foot,

A centimetre is more accurate than an inch,

A thou is more accurate than a centimetre,

and so on, and on.
